Caution Always use blanking panels to fill empty vertical spaces in the rack. This arrangement ensures proper airflow. Using a rack without blanking panels results in improper cooling that can lead to thermal damage.
Caution When selecting a rack to use, observe the following additional requirements to ensure adequate airflow and to prevent damage to the equipment: (1) Front and rear doors—If the 42U rack includes closing front and rear doors, you must allow 5,350 sq. cm (830 sq. in.) of holes evenly distributed from top to bottom to permit adequate airflow (equivalent to the required 64 percent open area for ventilation). (2) Side—The clearance between the installed rack component and the side panels of the rack must be a minimum of 7 cm (2.75 in.).

Temperature Requirements

To ensure continued safe and reliable equipment operation, install or position the system in a well ventilated, climate-controlled environment.

Ensure that the ambient operating temperature remains between 10 and 35° C (50 and 95° F), taking into account the elevated temperatures that occur when equipment is installed in a rack.

Caution To reduce the risk of damage to the equipment when installing third-party options: (1) Do not permit optional equipment to impede airflow around the mobility services engine or to increase the internal rack temperature beyond the maximum allowable limits. (2) Do not exceed the manufacturer’s maximum recommended ambient temperature (TMRA).

Power Requirements

Installation of this equipment must comply with local and regional electrical regulations governing the installation of information technology equipment by licensed electricians. This equipment is designed to operate in installations covered by NFPA 70, 1999 Edition (National Electric Code) and NFPA 75, 1992 (code for Protection of Electronic Computer/Data Processing Equipment). For electrical power ratings on options, refer to the product rating label or the user documentation supplied with that option.

Caution Protect the mobility services engine from power fluctuations and temporary interruptions with a regulating uninterruptible power supply (UPS). This device protects the hardware from damage caused by power surges and voltage spikes and keeps the system in operation during a power failure.

When installing more than one mobility services engine, you may need to use additional power distribution devices (PDUs) to safely provide power to all devices. Observe the following guidelines:

Balance the mobility services engine power load among available AC supply branch circuits.

Do not allow the overall system AC current load to exceed 80 percent of the branch circuit AC current rating.

Do not use common power outlet strips for this equipment.

Provide a separate electrical circuit for the mobility services engine.

Power Supplies on the Mobility Services Engine

The mobility services engine has two power supplies.

Warning This unit might have more than one power supply connection. All connections must be removed to de-energize the unit. Statement 1028

The mobility services engine comes with a universal rack mount kit that can be installed in a square-hole rack, round-hole rack, or a threaded-hole rack. You can order replacement universal rack mount kits from Cisco. The replacement part PID is AIR-SRVR-URMK=.

Note You must provide the threaded-hole screws to secure the mounting rails to the rack. Threaded-hole screws are not shipped with the system.

Review the documentation that comes with the rack cabinet for safety and cabling information. Before you install the mobility services engine in a rack cabinet, review the following guidelines:

Two or more people are required to install devices 2U or larger in a rack cabinet.

Make sure that the room air temperature is below 35° C (95° F).

Do not block any air vents; usually 15 cm (6 in.) of space provides proper airflow.

Do not leave open spaces above or below an installed mobility services engine in your rack cabinet. To help prevent damage to mobility services engine components, always install a blank filler panel to cover the open space and to help ensure proper air circulation.

Install the mobility services engine only in a rack cabinet with perforated doors.

Plan the device installation starting from the bottom of the rack cabinet.

Install the heaviest device in the bottom of the rack cabinet.

Do not extend more than one device out of the rack cabinet at the same time.

Remove the rack doors and side panels to provide easier access during installation.

Connect the mobility services engine to a properly grounded outlet.

Do not overload the power outlet when you install multiple devices in the rack cabinet.

Install the mobility services engine in a rack that meets the following requirement:

– Minimum depth of 70 mm (2.76 in.) between the front mounting flange and inside of the front door.

Caution Use safe practices when lifting.

Caution Do not place any object on top of rack-mounted devices.

The following illustration shows the items that you need to install the mobility services engine in the rack cabinet. If any items are missing or damaged, contact your place of purchase.

Note Some items come with the mobility services engine, not in the rack installation kit.

Note Use cage bars with square-holed racks, clip nuts with round-holed racks, and your own screws or the screws provided in this kit with threaded-hole racks.

Note If the slide rails in your rack installation kit came with shipping thumbscrews, remove them before you begin the following installation procedure.

Step 1 Select an available 1 U or 2 U space (depending on the mobility services engine you are installing) in your rack to install your mobility services engine. If you have either a round-holed or square-holed rack, install cage bars or clip nuts in the middle and the bottom (optional for the upper) holes of the lower U on each side of the front of the rack. Then, install cage bars or clip nuts in the upper and the bottom holes of the lower U on each side of the rear of the rack.

Step 2 Use a screwdriver to install the cage bars or the clip nuts on the inside of the mounting rail, as required for your rack, into the selected holes.

Step 3The rail depth can be adjusted from 17 in (432 mm) to 31.25 in (794 mm). To adjust the depth, you can loosen the nuts on the posts and slide the bracket until the distance between the front and rear slide rail flanges matches the distance between the front and rear EIA rails of the rack cabinet. If you need further adjustment, remove the nuts, move the bracket to the appropriate set of posts (A, B, C, and D) to obtain the appropriate slide rail depth, then reinstall and tighten the nuts.

Step 4To remove the support bracket, remove the screw (1) and remove the bracket (2) from the rear of the slide rail.

Step 5To remove the mounting brackets, remove the screws (1) and (3). Slide out the brackets (2) and (4) from the rear of the slide rail.

Step 6Attach the front of the slide rail and EIA latch to the front of the rack cabinet by installing a screw in the bottom hole of the lower U; then, install another screw in the middle hole of the lower U to attach the front of the slide rail to the front of the rack cabinet.

Step 8 Pull the slide rails forward (1) until they click, two times, into place. Carefully lift the mobility services engine and tilt it into position over the slide rails so that the rear nail heads (2) on the mobility services engine line up with the rear slots (3) on the slide rails. Slide the mobility services engine down until the rear nail heads slip into the two rear slots, and then slowly lower the front of the mobility services engine (4) until the other nail heads slip into the other slots on the slide rails. Make sure that the front latch (5) slides over the nail heads.

Step 9Lift the locking levers (1) on the slide rails and push the mobility services engine (2) all the way into the rack until it clicks into place.

Slide the system in and out twice to make sure the system slides correctly. Push the system inwards to the rack as close as possible but able to access the screws with a screwdriver. Then tighten the screws with a screwdriver.

Step 10 Slide the mobility services engine into the rack until it snaps into place. To slide the mobility services engine out of the rack, press on the release latches (1).

Note When you move the rack cabinet, or if you install the rack cabinet in a vibration-prone area, insert the optional M6 screws (2) in the front of the mobility services engine.

d. Rotate the tray handle to the closed (locked) position.

e. Check the hard disk drive status LED to verify that the hard disk drive is operating correctly. If the amber hard disk drive status LED for a drive is lit continuously, that drive is faulty and must be replaced. If the green hard disk drive activity LED is flashing, the drive is being accessed.

Replacing a Hot-Swap AC Power Supply

The following section describes the type of ac power supply that the server supports and other information that you must consider when you replace a failed power supply:

The Cisco 3355 Mobility Services Engine comes with two 675-watt hot-swap 12-volt output power supplies that connect to power supply bays 1 and 2. The input voltage is 110 V ac or 220 V ac auto-sensing.

Power supply 1 is the default/primary power supply. If power supply 1 fails, you must replace the power supply immediately.

You can order replacement power supplies from Cisco. The replacement part PID is AIR-SRVR-PWR=.

These power supplies are designed for parallel operation. In the event of a power-supply failure, the redundant power supply continues to power the system.

Caution The power control button on the device and the power switch on the power supply do not turn off the electrical current supplied to the device. The device also might have more than one power cord. To remove all electrical current from the device, ensure that all power cords are disconnected from the power source.

Caution Never remove the cover on a power supply or any part that has the following label attached. Hazardous voltage, current, and energy levels are present inside any component that has this label attached. There are no serviceable parts inside these components. If you suspect a problem with one of these parts, contact a service technician.

Step 2 Touch the static-protective package that contains the hot-swap power supply to any unpainted metal surface on the mobility services engine; then, remove the power supply from the package and place it on a static-protective surface.

Step 3 Remove the failed power supply first. Grasp the handle on the rear of the power supply and slide the power supply out from the chassis.

Step 4 Grasp the handle on the rear of the power supply and slide the power supply forward into the power-supply bay until it clicks. Make sure that the power supply connects firmly into the power-supply connector.

Step 5 Route the power cord through the handle so that it does not accidentally become unplugged.

Step 6 Connect the power cord for the new power supply to the power-cord connector on the power supply.

Step 7 Connect the other end of the power cord to a properly grounded electrical outlet.

Step 8 Make sure that the ac power LED and the dc power LED on the ac power supply are lit, indicating that the power supply is operating correctly. The two green LEDs are to the right of the power-cord connector.

Powering On the Mobility Services Engine

When you apply AC power to a mobility services engine, the bootup script initializes the operating system and its stored configurations. You are prompted to enter a user ID and password and enter key configuration details.

Follow these steps to power up the mobility services engine.

Step 1 Plug an AC power cord into the back of the two power supplies (Figure 2-5). If only one power supply is connected to a power source, the system will still function correctly but the monitoring components of the mobility services engine will detect the absence of the second power supply and send an alert to WCS. Connect the other end to a grounded 100 to 240 VAC 50/60 Hz electrical outlet.

The end of the power cord that plugs into the mobility services engine conforms with the IEC 320 standard.

Step 2 Use the front-panel Power On/Standby button, located in the operator information panel, to turn the mobility services engine on (Figure 2-2).

Step 3 At the login prompt, enter the mobility services engine operating user ID and password. The default user ID is root and the default password is password.

The user ID and password are case sensitive.

You are now logged into the mobility services engine operating system.

Configuring the Mobility Services Engine

Minimal configuration is done for the mobility services engine as part of installation using the console. All configuration beyond the initial setup using the automatic installation is done with Cisco WCS. For details on automatic installation refer to the “Automatic Installation Script” section.

Note You must change the default root password during initial configuration of the mobility services engine to ensure optimum network security.

You are prompted to change the password during the automatic setup script.

You can also change the password using the Linux command, passwd.

Automatic Installation Script

Note It is highly recommended that all relevant items be configured during initial setup to ensure optimum operation of the mobility services engine in your network. The hostname and either the Ethernet-0 (eth0) or the Ethernet-1 (eth1) port must always be configured during the automatic installation.

Note You can rerun the automatic installation script at any time to add or change parameters. There is no need to re-enter values that you do not want changed during one of these updates.

Note If you do not want to configure an item, enter skip and you are prompted for the next configuration step. Any setting skipped is retained and not modified.

The automatic installation script that displays to the screen is shown below along with descriptive text.

Example text: Indicates the installation script that displays to the console.

Enter Yes if you want to provide information for a second ethernet (eth1) interface.

Note Entry of a second ethernet interface (eth1) can be skipped by entering skip.

Note Communications between the mobility services engine, Cisco WCS, and the controller are in universal time code (UTC). Local time zones are configured on the mobility services engine to assist network operations center personnel in locating events within logs. Configuring NTP on each system provides devices with the UTC time.

Note The mobility services engine and its associated controllers must be mapped to the same NTP server and the same Cisco WCS server. An NTP server is required to automatically synchronize time between the controller, Cisco WCS, and the mobility services engine.

Network Time Protocol (NTP) Setup.If you choose to enable NTP, the system time will beconfigured from NTP servers that you select. Otherwise,you will be prompted to enter the current date and time.NTP is currently disabled.Configure NTP related parameters?

You can use an 8 character longpassword with characters from at least 2 of these 4 classes.An upper case letter that begins the password and a digit thatends it do not count towards the number of character classes used.Enter new password:Re-type new password:passwd: all authentication tokens updated successfully.Login and password strength related parameter setupMaximum number of days a password may be used : 99999Minimum number of days allowed between password changes : 0Minimum acceptable password length : 8Login delay after failed login : 5Checking for strong passwords is currently enabled.Configure login/password related parameters? (Y)es/(S)kip/(U)se default [Yes]: s

You can also configure a strong (Grand Unified Bootloader [GRUB]) password. A strong password must have a minimum of nine characters and must include two lowercase letters, two digits and two special characters (such as $ and #). An error message displays if you enter an inadequate password.

Caution If you forget the GRUB password, you cannot login and you will need to contact TAC to arrange for a Return Materials Authorization (RMA).

Note If a strong password is not enabled, a password can be of any length.

Note Passwords defined before a strong password is set are not affected by the strong password setting. Only those passwords that are set after the strong password is set are affected. For example, strong passwords will be required for passwords set later in this script, such as the Cisco WCS communication password (as noted in example below) and as passwords expire.

You can configure the WCS Communication username and password using the mobility services engine setup.sh script file.

Scenarios that you might encounter while configuring the WCS username and password are as follows:

If you configure a new WCS username and password, the password provided is applicable for the new WCS username created.

If you configure only a WCS username without configuring the WCS password, then the default password admin is applied to the configured username.

If you configure only a WCS password without configuring the WCS username, then the password for the admin user is changed.

If you configure an existing user name for the WCS username and also configure the password, then the password for that existing user is changed.

Note These users are API users, and they do not have corresponding OS users on the mobility services engine appliance.

Enter Y to enable and define a Cisco WCS communication password.

Note This password does not define an individual user password for access to the Cisco WCS GUI. This password is used for SOAP/XML authentication between systems (such as mobility services engines) and Cisco WCS.

Note It is recommended that you set a BIOS password to prevent unauthorized BIOS access.

All of the information that was entered into the install script appears on the screen.

Please verify the following setup information. ---------------------------------------------------------------------------Host name= mse-j05Eth0 IP address=172.19.35.236, Eth0 network mask=255.255.254.0Default gateway=171.19.34.1Time zone=America/Los_Angeles------------------------------------------------------------ You may enter "yes" to proceed with configuration, "no" to makemore changes, or "^" to go back to the previous step.

After the script configuration appears on the screen, you are asked to verify all the setup information you provided. You can enter Yes to proceed with the configuration, No to make more changes, or ^ to go back to the previous step.

Is the above information correct (yes, no, or ^):

If you enter yes, the configuration information is applied. Cisco recommends that you reboot the system when prompted to ensure that the changes are applied.

Note The message “***Configuration successful***” appears on the screen when the configuration is complete.

The next time you log in using root, only the Linux shell prompt appears and not the setup script. You can rerun the setup script at any time to change settings by logging in as root and running /opt/mse/setup/setup.sh.

The setup script generates a log file that can be found at /opt/mse/setup/setup.log.

Configuring an NTP Server

You can configure NTP servers to set up the time and date of the mobility services engine.

Note If you need to add or change an NTP server installation after a mobility services engine install, rerun the automatic installation script. You can configure the NTP server without adjusting the other values by tabbing through the script. To rerun the automatic script, log in as root and run /opt/mse/setup/setup.sh.

Note For more information on the NTP configuration, consult the Linux configuration guide.

Launching the Mobility Services Engine

To configure a mobility services engine to automatically launch after bootup, enter:

[root@mse-server1]# chkconfig msed on

To start the image manually, enter: /etc/init.d/msed start

Verifying the Mobility Services Engine Software State

You can verify the mobility services engine software state at any time. In the mobility services engine CLI interface, enter: /etc/init.d/msed status.

If the mobility services engine is running, the command output looks like this example:

Step 3 Click the name of the mobility services engine to which you want to download software.

Step 4 Choose Maintenance (left panel).

Step 5 Choose Download Software.

Figure 2-11 Mobility Services Window

Step 6 To download software, do one of the following:

To download software listed in the Cisco WCS directory, select Select from uploaded images to transfer into the Server. Then, choose a binary image from the drop-down menu.

Cisco WCS downloads the binary images listed in the drop-down menu into the FTP server directory you have specified during the Cisco WCS installation.

To use downloaded software available locally or over the network, select the Browse a new software image to transfer into the Server and click Browse. Locate the file and click Open.

Step 7 Click Download to send the software to the /opt/installers directory on the mobility services engine.

Step 8 After the image has been transferred to the mobility service engine, log in to the mobility services engine CLI and run the installer image from the /opt/installers directory by entering the ./image-name command.

Manually Downloading Software

If you do not want to automatically update the mobility services engine software using Cisco WCS, follow these steps to upgrade the software manually using a local (console) or remote (SSH) connection.
